I also have the same problem - no URL generated, and in my case, hitting the run button takes me to a blank page (the code is not accessed). This is a repo that I am co-managing with one other person. Is there a way to check there isn’t also an error in the repo? https://pavlovia.org/leipsy/scheduler. Please let me know if you’d need other info. Thank you so much!
Also, I wasn’t sure where people would reply so I also replied to this post: No URL on Pavlovia
